Beit known that Gnome WALTER Non- GATE, a citizen ofthe ted States, residing of Cook and State Improvements in Electric Signal Bevices, of "which the iioiiowing is a fail, clear, concise, and exact description, reference being had to the accompanying drawing, forming a part of this specification.

My invention relates to electric signal do; vices, and speeificaiiy to the type of said devices known as huzzers.

@ne of the objecs' o my invention is to provide'an electric si ti device or" this type wherein the Yihi'a" U ineinher a'iso series as hou'sing'for eiectroinagnet.

Afurther object of my inYention is to im prove upon the detaiis oit' construction of an. eiectroniagnet signai device.

An electric signai device constructeti in accoi'ci arce with my invention is described, by way of example, in the foiio'wing spec fication and shown iurcoznpang' drawings. It is to be understood, however. that my invention may he embodied in sig' nai devices of other types than that (iiiscribed and shown, and at c1 may 1 l 1' be made in the construct. 3. have scope of the invention as cieiine-(i the ap- In the drama a ricw substana modification oi i a .41. e chrae logs one.

In the modification ofFig. 2 the base 10 has secured thereto by means of rivets 18 a dish-shaped sheet metal housing 19 The alternations of current in the eiectr'oinagnet 11 cause the upper fiat part of the housing to vibrate, this part being 10- cated so near thecore l2 ofthe electromag- 7e net that it strikes i it vibrates, thus producing a hammering noise in ad tion to the buzzing noise produced by the vibrations of the fiat part.

It will benoted that the base 10 is dished on the'iower side and hence acts as a re tor when the dished ho'i'ising w strikes Having thus described my invention What i claim as new and desire to secure h Let ters Patent, isso 1.
